Filed: 1987-05-15
Abstract: PURPOSE:To equalize a waveform with a simple constitution by differentially amplifying an input signal, obtaining two output waveforms whose polarities are inverted, differentiating one, attenuating the other and giving it to a differential amplifier. CONSTITUTION:A head output waveform is amplified by a differential amplifier 11 and two output waveforms whose polarities are inverted are obtained. The one output out of the two is differentiated by a differentiator 12 and after a main pulse, comes to be a waveform to have a sub pulse. The other output of the amplifier 11 is attenuated by a gain adjusting circuit 13. With this attenuated pulse, by adjusting an attenuation coefficient so that the sub pulse of the inverted polarity, after the main pulse, can be canceled, the output of the differential amplifier 14 to input the outputs of the differentiator 12 and an attenuator 13 is equalized to a single pulse to have a satisfactory symmetry. Thus, with a simple constitution, an asymmetrical dipulse waveform is equalized to the single pulse and a peak shift due to a waveform interference can be reduced.

Abstract: PURPOSE:To prevent the breakdown of a memorized content due to an effect of ultraviolet rays, etc. contained in natural light, and to rewrite the memorized content selectively and easily through an erasing means such as the irradiation of ultraviolet rays by polarizing light by using a liquid crystal. CONSTITUTION:A semiconductor memory cell 1 is die-bonded with a substrate 2, and sealed by a cap 9 having a douser 13 while being opposed to the cell surface of the cell 1. The douser 13 is manufactured in such a manner that a transparent conductive film 16 and an orientation film 17 are formed onto a plate 15 excellently transmitting light, a surface to which the film 16 and the film 17 are formed of the transmitting plate 15 is opposed at a proper interval and the liquid crystal 18 is enclosed. A writable ROM (an EPROM) of such constitution does not pass natural light so far as an electric field is not applied to the liquid crystal 18, and the breakdown of the memorized contents due to ultraviolet rays, etc. can be prevented. The memorized contents can easily be erased because light can be conducted excellently to the cell 1 only by applying an electric field to the liquid crystal 18. The EPROM can also be rewritten partially.

Title: Manufacture of semiconductor device
Inventor: HONMA KAZUYA
IPC: H01L21/316
Filed: 1995-05-17
Abstract: PURPOSE:To provide a manufacturing method of a semiconductor device with an inter-layer insulating film, which has no possibility that the hot carrier resistance of a transistor is not deteriorated, in addition to excellent flatness. CONSTITUTION:An ion implanting layer 10 is formed onto the surface of a plasma TEOS film 9, and an ozone TEOS film 11 is formed. Since there are a large number of dangling bonds in the ion implanting layer 10, the dangling bonds capture moisture, thus inhibiting the permeation of moisture. Consequently, the plasma TEOS film 9, in which the ion implanting layer 10 is shaped on the surface, has the extremely high permeation inhibition effect of moisture. Accordingly, moisture contained in the ozone TEOS film 11 does not permeate the plasma TEOS film 9, and there is no possibility that the hot carrier resistance of an IGFET formed onto a substrate 1 is deteriorated by moisture. That is, the hot carrier resistance of the IGFET can be improved as the ozone TEOS film 11 remains flat.

In this case, as a representative printing base material 2, a polyvinyl chloride resin sheet which is a base material for articles being used for so-called cards is normally used because of the suitability for a printing and a working, and paper and a metal foil or the like are used other than the sheet.  Also, the pattern layer 3 is constituted in such a manner that at least one section of the pattern layer 3 may be dissolved and collapse together with the dyable layer 4 when the image 5 is tried to be removed by making a solvent react with the receiving layer 4 having the image 5.
